SADDLE RIVER, N.J. (CBSNewYork) — A crafty cat burglar is causing chaos in some leafy New Jersey suburbs. Jewelry, cash and, in some cases, high-end cars have been swiped right in the middle of the day.

As CBS 2’s Tamara Leitner reported Friday, police are warning residents in Saddle River and nearby towns to lock up their valuables.

They are a brazen series of crimes and not the type of things residents said they expect to find in their upscale community.

Police said there’s a cat burglar prowling the well-manicured streets. The thief has boldly struck five homes — while the residents were home.
